Detailed explanation-1: -The phosphorus cycle does not have a gaseous phase.

Detailed explanation-2: -Unlike the compounds of other matter cycles phosphorus cannot be found in air in the gaseous state. This is because phosphorus is usually liquid at normal temperatures and pressures. It is mainly cycling through water, soil and sediments. In the atmosphere phosphorus can mainly be found as very small dust particles.

Detailed explanation-3: -The phosphorus cycle does not include a gaseous phase, resulting in no significant quantities of atmospheric phosphorus. Explanation: The phosphorus cycle does not contain an atmospheric phase, while both the sulfur and nitrogen cycles do.

Detailed explanation-4: -The phosphorus cycle does not have a gaseous phase.

Detailed explanation-5: -Unlike nitrogen, the phosphorus cycle does not have a significant atmospheric component. A chemical distribution of phosphorus between aquatic and particulate components occurs via, e.g., adsorption and precipitation processes.
